Mr James John Mnyonga

I am a Forester with particular interest in Agroforestry Research on the interaction of people, agriculture and trees to the scales from eco-physiological interactions among system components to landscape level effects, across tropical environments, with a focus on multipurpose tree species and farm trees. I earned my M.Sc. in November 2005 from Sokoine University of Agriculture. My dissertation focused on the response of 5 leguminous shrubs and cow manure on soil fertility and subsequently maize production in the semi-arid area of Tanzania where I spent two years in the field. I believe that interdisciplinary approach is key to solving agroforestry challenges. My graduate career has given me the opportunity to work on a variety of projects, including PETREA project from Denmark, MITIMIOMBO project from Finland and several from Tanzania. My specialization is in:

  • Role of trees in the agricultural landscape
  • Formal representation of local ecological knowledge
  • Tree-crop-soil interactions
  • Domestication of indigenous tree species
  • Beekeeping
